4T0 all whom it may concern:

Be it known that we, W LLIAM A. LORENZ and WILLIAM H. HoNIss, both of Hartford, Connecticut, have jointly invented certain new and useful Improvements in Paper Bags,

ofwhich the following description and claims constitute the specification, and which are I of said generic process.

Figure 1 of the drawings is a plan View of a fiat paper tube of suitable length to make a paper bag, and having slits out therein preparatory tomaking a satchel-bottom paper bag having either of two specific forms of our improved bottom. Fig. 2 is a View of the lower end of the fiat paper tube of Fig. Fig. 3 is a View of the flat tube of Fig. 1, with the thumb-notch coinpleted,and with the 'first fold in the process of making the bottom properly made. Fig. 4 is a'view of the blank of Fig. 3, with paste applied to the upper and to the lower flap. Fig. 5 is a view of the blank of Fig. 4, with the lower flap folded over. Fig. 6is a view of the blank of Fig. 5, with the upper flap folded down, and the bag thus completed. Fig. 7 is a perspective view of the bag of Fig. 6, opened out. Fig. 8 is a view of the inside of the bottom'of the bag of Fig. 7. Fig. 9 is a perspective view of a second specific paper bag, made from the flatpaper tube of Fig. 1, in a manner hereinafter described. Fig. 10 is a plan View of a flat paper tube of suitable length to make a paper bag, and having slits cut therein prepar- 0' atory to making a satchel-bottom paper bag having either of two other specific forms of our improved bottom. Fig. 11 is a View of the lower end of the fiat paper tube of Fig. 10. Fig. 12 is. a view of the fiat paper tube of Fig. 10, with the thumb-notch completed, and with the lower end of the tube opened up and folded, as hereinafter described. Fig. 13 is a view of the lower end of the blank of Fig. '12. Fig. 14 is a view of the blank of Fig.-12,'with Serial No. 134.959.- (No model.)

the side flaps folded down. Fig. 15 is a view of the blank of Fig. 14, with paste applied to the outer surfaces of the side flaps. Fig. 16 is a view of the blank of Fig. 15, with the lower'flap folded over. Fig. 17 is aview of the blank of Fig. 16, with paste applied to the outer surface of the lower flap. Fig. 18 isavie w of the blank of Fig. 17, with the upper flap folded down, and the third specific bag thus completed. Fig. 19 is a perspective view of the bag of Fig. 18 opened out. Fig. 20 is aperspective View of a fourth specific paper bag, made from the'flat paper tube of Fig. 10, in the manner hereinafter described in that behalf. Fig. 21 is a plan View of a tucked paper tube of suitable length to make a paper bag, and having slits cut thereinpreparatory to making a square-bottom paper bag having either of two specific forms of our improved bottom. Fig. 22 is a View of the lower end of the tucked paper tube of Fig. 21. Fig. 23 is a view of the tucked paper tube of Fig. 21, with the lower end of the tube opened up,as hereinafter described. Fig. 24. is a View of the lower end of the blank of Fig.'23. Fig. 25 is aview of the blank of Fig. 23,with the side flaps folded down in their permanent places, and with the top and the bottom flap folded temporarily backward. Fig. 26 is a view of the blank of Fig. 25,with paste applied to the presented surfaeesof the upper and lower flaps. Fig. 27 is a-1view of the blank of Fig. 26,with the lower flap folded down in its permanent place. Fig. 28 is a view of the blank of Fig. 27, with the upper flap folded down upon the lower flap, and the fifth specific bag thus completed. Fig. 29 is a perspective view of the bag of Fig. 28,0pened up. Fig. 30 is a perspective view of a sixth specific bag, made from the tucked paper tube of Fig. 21, in a manner hereinafter described. Figs." 31 and 32 are perspective views of a seventh and an eighth specific bag, either of which may be made from a blank identical with that of Fig. 21, except that to make either of them the lateral slits of that blank must be cut into the adjacent parts of the 'tucks,instea'd of int-o the upper and lower sides of the tube;

Ais ashort longitudinal slit cutin the middle of theupperedge of one of the sidesiof the,

flat paper tube of Fig. 1.

B and G are short longitudinal slits cut in the upper edge of one of the sides of the fiat paper tube of Fig. 10.

D and E are right-angled slits cut in the:

lower edge ofboth sides of the flat paper tube lateral parts of the slits D and E extend to-.

- ward each other; but the lateral partsof the slits F and G extend away from each other.

H, I, J, and K are right-angled slits cut in, the lower edge of the tucked paper tube of Figs. 21 and. 22. Thelongitudinal, parts of.

these slits are in the convex folds of the tucks, as shown in Fig. 22, and are on aline with the future corners, respectively, of the bags when opened out, as shown in Figs. 29, 30, 31, and 32. The lateral parts of these slits extend from the inner ends of the longitudinal parts,-

respectively, 'and toward each otherasfar as the short dotted lines in Fig. 22.

L is the lowerand M is the upperflap, while N and O are the side flapsofeach of the several specific bags shown in thedrawings.

P is the paste,whieh is applied to sundry of the flaps, as shown.

Q represents the only portions of the bot. toms of the variousbags where only one thick-- ness of paper exists.

R and R are the triangular folds of oneform of thumb-notch, while S is that thumb-notch. T is the quadrangular fold of another form,

of thumb-notch, while Uis that notch.

The method of folding the bottom of the.

first specific bag isas follows: The upper flap, M, and the adjacent partof the flatpapentube of Fig. 1 arefoldedback on the line V-V of .Figs'. 1, 3, 4, 5, and 6. At the'same time the flaps N and, O arefoldedon the four diagonal linesshown in Fig. 3. Paste is then applied to the presented surfacesof theflaps, substan; tially asshown'in Fig. 4, andthenthe flap L .isfolded over on the line W1W of-Figs., 3 and 4 into the position shown in Fig.5.. Then the flap Mis folded .down on the line X XofFigs.

1, 3, 4, and 5 into the positionshown in' Fig.5. The method of folding thebottom-offthe sec:

,. ond specific bag is, as follows The flaps'L, M,

Figs. .12 and 13. Then the flaps vL and -M;are

' folded down, and paste is appliedfto the' bop-g.

N, and O of the .flatpaper tube ofFig. 1 are.

opened up into the box-like formshown in folded down, one after the other, leaving the othersides of the box-like for-mv Standing, Paste is then applied tothe, presentedsur'faces,

of the flaps, L and M. I Then the fiapO is der-of its end. Then the fiap Nis folded down upon'the other three flaps, and the bottom of the bag shown in Fig. 9 is thus completed, ready to be opened out into the form shown in that figure. The method of folding the bottom of the third specific bag is as follows: The flaps L, -M, N, and O of the fiat paper tube of Fig. 10 are opened up into the box-like form shown in Figs. 12 and 13. Then the flaps N and O are folded down, one after the other, leaving the other sides of the box-like form standing, as shown in Fig. 14. Paste isthen applied to the presented surfaces of the flaps .N and O, as shown in Fig. 15. Then the flap Lis folded down, as shown in Fig. 16, and paste is then applied to the border of its end, as shown in Fig. 17. Then the flap M is folded down upon the other three flaps into the position shown in Fig. 18. v

The method of folding the bottoinof the fourthspecific bag is as follows: Theflaps L, M, N, and O of the fiat paper tube of Fig; 10 are opened up into the box-like formshown in Figs. 12 and 13. Then the flaps-L and M and the flaps N and O are folded down, and

- paste is applied precisely as in the method of 7 making the bottom of the second specific bag hereinbefore set forth.

The method of folding the bottom of the fifth specific bag is as follows: The flaps-.L,'M,

N, and O of the tucked paper tube of Fig. 21

- are opened up into the box-likeform shown ,1I 1-F1g'S..23 and 24. Then the fiaps .,N and O are folded down,,one after the other, leaving presented. surfaces, as shown in Fig. 26. Then the fiapL is folded over on the line W W of ;Figs. 25 and 26 into the positionoshown in Fig. Then the flap M isfolded over. on the hue X X of Figs. 25 and 26 into the position shown in Fig. 28. Thermethod of folding the bottom of the sixth specific bag is as follows: Theflaps L,

M, N, and Oof the tucked papertube of Fig. 21 are opened up into the box-like form'shown inFigs. 23 and 24. Then the .fiaps L and M are folded down,?,one. after the other, ,leaving. the other sides of the box liketform standing. Then paste isappliedjto-the presented surfaces of the flaps L and M. -Then the flap Ois folded down, and pasteis applied to the border of its end. ,'..Then the flap and the bottom of the bag shown in I Fig. 30

,is thus-completed, ready to be .opened out into .the form shown in that figure.

Themethod of .folding the bottom f the seventhspecific bag. is as followsz-qllhfigflaps L, M,,N, and O ofa blank identical-with that of Fig. 21, except in having t e lateral ,partsof the slits H, I, J, andK cut, into the adjacent parts of the'tucks, instead o; f{- into the upper andlower sides of the pap er ..;tube,

.Nlis folded down upon the. otherthreefiaps,

are opened up into the box-like form shown in Figs. 23 and 24. Then the flaps N and O are folded down, one after the other, leaving the other sides of the box-like form standing. Then paste is applied to thel presentedisurfaces of the flaps N and 0. Then the flap L is folded down, and paste is applied to the border of its end. Then the flap M is folded down upon the other three flaps, and the bottom of the bag shown in Fig. 31 is thus completed, ready to bejopened out into the form shown in that figure. I

The method of folding the bottom of the eighth specific bagigisjas followsQTheiflaps L, M, N, and O of a blank precisely like that used to make} the seventhlspecific bag are opened up into the box-like form shown in Figs. 23 and 24. Then the flaps L and M are folded down, one after the other, leaving the other sides of the box-like form standing. Then paste is applied to the presented surfaces of the flaps L and M. Then the flap N is folded down,{and paste is applied to the border, of its end. Then the flap O is folded down upon the other three flaps, and the bottom of the bag shown in Fig. 32 is completed, and may be opened up into the form of that figure.

We claim as our joint invention- 1. The process of making the bottom of a o paper bag, which consists in first cutting four angular slits in the lower edge of a paper tube, the longitudinal parts of which slits are respectively on a line with the future four corners of the body of the bag, respectively, and then in folding the four flaps thus made and pasting them in place in the manner particularly set forth in the foregoing description and illustrated in the accompanying drawings.

2. A paper bag the bottom of which is composed ofzfour flaps, each of which is integral with the body of the bag, and all of which are formed by cutting four angular slits in the lower edge of a paper tube, the longitudinal parts of which} slits are respectively on a line with the four corners of the body of the bag, respectively, and all of which flaps are folded and pasted in place in the manner particularly set forth in the foregoing description and illustrated in the accompanying drawings.
